131. If the NRA claims they preach keeping guns at home LOCKED UP and secure to prevent accidents

imagine what steps would be needed at a place like a SCHOOL? There would be so many stages of accessing and loading a firearm in a school, there would be no way a teacher or administrator could be battle-ready when a gunman is unloading at people.

So, explain to me again how arming everyone in a school would have prevented this and other mass shootings at schools?
